Machine learning is playing an increasingly important role in many areas of our businesses and our lives and is being employed in a range of computing tasks where programming explicit algorithms is infeasible. At Amazon, machine learning has been key to many of our business processes, from recommendations to fraud detection, from inventory levels to book classification to abusive review detection.

In this article I am going to show you two approaches to load balance JAXRS web services without an Apache or a hardware load balancer. The full code is available on GitHub. CXF provides clustering strategies which can be used for configuring a load balancer which has already been discussed here. However, load balancing the JAXRS requires a little more effort, which I have described in this article.

As some of you may know, I have a hoarding problem. I am hoarding Raspberry Pi microcomputers. In my personal collection I have one from each generation, making four standard units. Well, I recently picked up another unit, but this time a Raspberry Pi Zero. These things are about the size of a nine volt battery, but pack some serious punch. The problem is they are incredibly rare because they retail for only $5.00.

Often when monitoring and debugging site performance we focus on network activity and individual resources, but what about the CPU? As more and more sites switch to using large Javascript frameworks and manipulating the page using Javascript, the execution time this code takes and the available CPU can instead become the performance bottleneck. CPU usage for all Chrome tests.

It’s no secret that I have reservations about Google’s AMP project in its current form. I do want to make it clear, though, that what bothers me has never been the technical side of things—AMP as a performance framework. The community working on AMP is doing good work to make a performant baseline. As with any framework, there are decisions I agree with and some I don’t, but that doesn’t mean the work isn’t solid—it just means we have different ways of approaching building for the web.

Estimates are waste. Not only are they not necessary, but they introduce dysfunction into the team. We should really just stop doing them. This thinking comes from the #NoEstimates movement (of which I’m a card-carrying member), which came onto the scene a couple years ago when @WoodyZuill created the #NoEstimates hash tag on Twitter.

As there are more and more things being connected to the Internet, necessarily there is a need to integrate these devices together. We have some great opportunities to be really productive in partitioning huge problems into small and even smaller and solve them one by one. We can easily develop a simple service, put it into a Docker container and deploy it to any cloud solution.

As many of you know, I had been using Apache Cordova based frameworks such as Ionic Framework for a long time. They are convenient and easy to use when it comes to rapidly developing cross platform applications. The problem with using Apache Cordova frameworks such as PhoneGap, Ionic Framework and Onsen UI is the performance limitations that come with them, particularly because of their use of the platform web view.

Progressive Web Apps (PWAs) combine the best and newest features of the Web to deliver an experience that rivals native applications on mobile. Even better, they work on desktop, too. In fact, they work everywhere that the Web works! "Ah", you say, "that's not true! They require features that don't exist in all browsers." Because PWAs are "progressive", they can adapt to older browsers to deliver the best experience possible given the features that are available.

UPDATE 2016-12-25: This post has an important follow-up. At some point in every software developer’s career, we work with someone who does negative work. The notion of negative work may sound a little strange. Someone can do no work by just… not working. How does negative work happen? One example of this is an awful developer that was once at the same company as me.

Recently, there some was some confusion between myself and a coworker over the definition of a “word.” I’m currently working on a blog post about data alignment and figured it would be good to clarify some things now, that we can refer to later. Having studied computer engineering and being quite fond of processor design, when I think of a “word,” I think of the number of bits wide a processor’s general purpose registers are (aka word size ).

Sometimes two is better than one. In pair testing, two people sit behind one machine to test the software. One person controls the mouse and keyboard. The other person asks questions, discusses test scenarios, and takes notes. Pair testing is a type of exploratory testing, where two team members discuss and share ideas and scenarios around the software.

One of the very first projects I ever worked on as a professional was a relatively large site with tons of legacy code. Legacy code brings many headaches. My favorite example was opening a few pages to find that these pages used not one, not two, but three different JavaScript frameworks! The developers were overworked and the site had never gotten enough budget to give it the rebuild it needed.

Continuous integration (CI) and continuous deployment (CD) are terms that I hear thrown around quite frequently. I’ve been a software developer for a long time, but it is only recently that I’ve welcomed these terms into my life. CI and CD is the automated process of running various tasks such as unit testing or building a version controlled project.

SpeedCurve’s sweet spot is the intersection of design and performance - where the user experience lives. Other monitoring services focus on network behavior and the mechanics of the browser. Yet users rarely complain that “the DNS lookups are too slow” or “the load event fired late” Instead, users get frustrated when they have to wait for the content they care about to appear on the screen.

Developer/coding bootcamps are incredibly popular right now. That should not be a surprise to anyone. Software development is an incredibly lucrative field. There is a much greater demand for talent than there is supply. I’ve seen that from both the hiring side and the job applicant side. It makes sense that a lot of folks out there are interested in becoming software developers.

This post is a follow up to my previous blog post about word size. Three C/C++ programmers walk into a bar. One argues that sizeof(void*) is equivalent to sizeof(long), one argues that sizeof(void*) is equivalent to sizeof(int), and the third argues it’s sizeof(long long). Simultaneously, they’re all right, but they’re also all wrong (and need a lesson about portable C code).

The software development life cycle is complex. Among the many moving pieces of developing software is the process of testing. Testing ensures quality in the product and proves the code is functioning as expected and as needed. There are many different testing activities that should occur within the process of building software. User Acceptance Testing, or UAT, is just one of the various types of testing involved in the software development life cycle, and most commonly, it is the final testing
